My wife's [32F] best friend [32M] hates me. We're running into problems after the birth of our child. I [33M] don't know how I feel about him still being around.

My wife and I have been married for 3 years and three months ago she gave birth to a beautiful baby girl. Our personal relationship has never been better and I'm absolutely in love with my family.
The one small, nagging problem is her best friend. She's known this guy since they were in college, well over 10 years. He used to live very far away from us and she saw him maybe once a year. My wife says they never dated and I 100% believe them. I've been with them a lot and there is literally not an ounce of sexual tension/chemistry. They're like siblings.
I've known since the beginning that he doesn't like me. My wife and I are very different than him. He has a ton of friends but they are, again...different than us. We don't run in the same crowds so it's kind of natural that he doesn't like me. I think he just likes my wife because they have so much history. I really don't know why they're so close, but they are. It's inexplicable. She "keeps him in line", so to speak. She doesn't tolerate him bad-mouthing me and has never put his needs/feelings ahead of my own. I'm fine with him. He's harmless. Our arrangement has been that she can hang out/talk with him and I really don't have to be his friend. It's a good arrangement.
A year ago he moved to the same city and they started hanging out in increasing amounts. I was really happy for my wife. She doesn't have a ton of friends and I could tell she was really glad to have her best friend nearby. They hang out maybe once a week.
When my wife reached the 6 months pregnant mark I noticed things changing a bit. Her friend got super protective. He was stopping by the house frequently to drop off baby things, giving her articles he'd found about the best way to do whatever, and almost every Saturday he was wanting to take her out shopping or just hang out around the house.
When our daughter was born things didn't dial down. He was constantly over to see his "niece". He adores our daughter, and I have to admit he's really good with her. But he still hates me. Whenever he's over I'm ignored. I might as well not exist. When talking about the baby I'm never mentioned, it's her and my wife.
My wife does good, I can't fault her. She tells him to say to me, tells him to stop ignoring me, etc.
But I feel weird. I feel like it's weird to have a dude be such a big part of my baby's life when he won't even speak to me. I also have this weird irrational worry that when she gets older he's gonna, like, turn her against me or something. Irrational, I know.
I just don't know what to do. I'd never want to tell my wife to not see him. She needs friends and he is a great friend to her. She thinks I should try to get to know him better. I say that if it hasn't happened in the last 8 years it isn't happening now.
What do I do? Are there options to keep us both happy?

tl;dr: My wife's best friend hates me. He adores our daughter. I feel weird. How do I keep my wife happy while not feeling weird about his role in our lives?
